The links o* are made adjustable in order that the renters of the blanks and of the platen may beI iliade to register in a liorizontzil plane and the regislration thereof in a vertical plane is accomplished b v the l1orizoiual adjustment of the guide m, Wliirh adapted to be secured in any desired posilion upon a transverse fixed shaft ni? upon the carriage and, as previously explained,

if no blank should be engaged by the block le, no printing results.
